The effect of reversible inactivation of raphe nuclus on learning and memory in rats

The role of raphe nucleus (R.N) and serotonin in some behaviors such as sleep, cognition, mood, and memory has previously been reported. The median raphe (MR) nucleus is a major serotonin-containing cell group within the brainstem and is one of the main sources of projections to the septum and hippocampus. The hippocampus is widely believed to be essential for context-conditioning learning. Mor...

Reversible inactivation of dehydrogenases.

1. The reversible dissociation of lactic and malic dehydrogenases has been studied in detail and compared with the dissociation properties of triosephosphate dehydrogenase, a-glycerophosphate dehydrogenase, and liver alcohol dehydrogenase. 2. Evidence is presented for the existence of an intermediate form of lactic dehydrogenase with catalytic properties altered during reactivation. 3. The tech...

PROTAMINE PURIFICATION OF STREPTOKINASE AND EFFECT OF pH AND TEMPERATURE ON REVERSIBLE INACTIVATION

1. Treatment of crude concentrates of streptokinase with protamine results in removal of about 90 per cent of the nitrogenous material, including nucleic acid and protease inhibitor, with little or no loss of activity. 2. Streptokinase solutions undergo reversible inactivation with changes in pH. The rate and extent of inactivation are dependent on pH, being greatest over a very narrow range ab...
